113603-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113603-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,6,0 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 113603-23:
(8*1)+(7*1)+(6*3)+(5*6)+(4*0)+(3*3)+(2*2)+(1*3)=79
79 % 10 = 9
So 113603-23-9 is a valid CAS Registry Number.

CONVENIENT SYNTHESES OF CYCLIC CARBONATES BY NEW REACTION OF OXIRANES WITH β-BUTYROLACTONE
Nishikubo, Tadatomi,Iizawa, Takashi,Iida, Makoto,Isobe, Naoki
, p. 3741 - 3744 (2007/10/02)
Cyclic carbonates were synthesized by reactions of the corresponding oxiranes with β-butyrolactone using quaternary salts such as tetrabutylammonium bromide or 18-crown-6=KBr as catalyst.
